let me start with you, senator mccain. guns in america, should anything be done or are you comfortable with where things are? >> actually, i'm comfortable. i think that, for example, the killing that has aroused mr. costas' anger was an act of hatred and brutality, and that person wanted to kill somebody, they didn't need a gun to do it. so look, i just believe that it's one of our rights and -- joe? >> i start with the belief that the second amendment actually does protect the right of individual americans to own guns, but in my opinion, it's no more unlimited than the right of free speech which has limits. so i've supported, for instance, bans on the automatic weapons and for a while we've been trying to close what's called the gun show loophole. if you go in a store, it's pretty regulated now, to buy a gun at a regular gun shop there's a check done on you and national computer file of criminal records or if you can mental health records or indications of violence. if you go to a gun show, you don't have to do that. that
